How Does SPROG II Work?

SPROG II gives you the ability to program DCC decoders using your computer without the need to move your computer to the railway room, or your existing DCC system to the computer room.

SPROG II accepts commands from the computer port and formats them into DCC packets for programming of decoders or operating small layouts or DCC accessory systems.

To use SPROG II with DecoderPro, simply follow the instructions on the DecoderPro web pages for SPROG. SPROG II documentation is available from the download page (see menu at left).

SPROG II should work with any DCC decoder conforming to NMRA standards. We have had few reports of any specific problems. We have had positive feedback that SPROG II definitely works with the following. However this is only a partial list.

We always appreciate further feedback of decoder types that have been tried and will add them to the list.
